A bit tangential to your point but firefox for android isn't bad. I am using it to type this.

Not as snappy or polished as chrome on android to be honest.

I personally switched to it because I felt I give enough data to Google as it is. Probably not a great reason, because they still get a lot of data from me.

Sure, I use Firefox for Android as well. The "no one" was for ease of illustration; the general point is that Firefox market share on mobile is different from desktop and that this affects per-view share more than per-user share. Of course, to the extent that someone only uses a mobile device to access the web, per-user share is affected too.
